Knowing My CPU

hey, sorry to bother you guys about this, but I just ordered a custom computer from a store, and I was wondering if there is a way to tell wether the CPU (intel) is the HT ones. The reason im asking is because im afraid of them ripping me off with just a normal 3.2 CPU instead of the ones with hyper-threading. So if anyone can tell me how to see what type it is it would be great =).

The very simplest way is to check the number of CPUs
displayed by the task manager (assuming windows XP). If you
have only 1 CPU, but there are 2 CPUs shown, there is a
good chance that you have HT support (real vs logical CPUs).

Also simple might be to remove the cooler, look at the CPU for
a small HT, and put back the cooler correctly (not recommended)

The second simplest, but safe way would be to use the intel
tool at [1].

For those interested in what the tool is actually doing.
It calls cpuid and obtains information by analysing the
result (in edx) based on the specification[2].
I quickly coded an example (for several compilers)
